Summary
Cutaneous infiltration by B-cell chronic lymphocytic leukemia (B-CLL) presented as a rare zosteriform rash. Treatment targeting the leukemia led to complete resolution of skin lesions and symptoms.
Area of Science:
- Dermatology
- Hematology
- Oncology
Background:
- Cutaneous leukemic infiltration is an uncommon sign of disease progression.
- B-cell chronic lymphocytic leukemia (B-CLL) can manifest in the skin, though rarely with a zosteriform pattern.
Observation:
- A 77-year-old female with B-CLL presented with a 4-week history of pruritic, erythematous papules on her left hemithorax in a C6 dermatome distribution.
- Initial treatment for viral infections (Valacyclovir, Acyclovir) was ineffective.
- Tzanck smear and PCR for VZV/HSV were negative.
Findings:
- Histopathology revealed a B-CLL infiltrate (CD3+, CD20+).
- Cytogenetic analysis confirmed bone marrow alterations consistent with cutaneous B-CLL infiltration.
- The patient responded well to chemotherapy with chlorambucil and IV immunoglobulin, achieving complete regression of lesions and pruritus.
Implications:
- This case highlights a rare presentation of cutaneous B-CLL infiltration mimicking herpes zoster.
- It underscores the importance of considering underlying hematologic malignancy in atypical dermatological presentations.
- Therapeutic strategies should focus on treating the primary leukemia for effective management of cutaneous manifestations.

Primary Lymphoid Organs
Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

Secondary Lymphoid Organs
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Lymphoid Cells and Tissues
Lymphoid cells and tissues are integral to the immune system, which is crucial in maintaining our body's defense against harmful pathogens. They form the building blocks of lymphoid organs, which include the spleen, thymus, and lymph nodes.
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...

Disorders of Leukocytes
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...

Detailed Structure and Function of Lymph Nodes
Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
